ActiveObjects NameConverters for tests Edited

This commit from 2011 (!!) removes the TestActiveObjectsFieldNameConverter.java and TestActiveObjectsTableNameConverter.java which are still referenced in this tutorial (at the bottom of the page).

Have these Converters been moved to another repository? Or Should other converters be used in tests now? Or is the use of the @NameConverters annotation as described in the tutorial obsolete altogether?

Thanks for any hint on this!

PS: to clarify, in case the classes were moved I am not so much interested in the new repository, but rather in the maven dependency required to use the classes.
